sowing date and irrigation are two constrain factors for maize production. these factors can be simulated by using ceres-maize model. for this purpose two experiments (each one at two years) were carried out at agricultural research station of gorgan which is golestan province capital. the model was calibrated using three treatments of optimum irrigation and without stress in 2012 and two treat...

in order to investigate the effects of on-farm seed priming and sowing dates on seedling emergence, yield and yield components of a local genotype bean called pach baghala-red strain (phaseolous vulgaris l.) as a double crop after rice, an experiment carried out in the rice research institute of rasht. experimental design was laid out in a split plot based on a randomized complete block with th...

Current research was conducted during 2006 and 2007 cropping seasons to assessment the anatomy of the flag leaf and yield of rice in the Khuzestan province according split plot experiment based on randomized complete block design with three replications. Main plot included different sowing dates at three levels (5 May, 26 May and 16 June). Hoveizeh, Hamar (Heat tolerance), Ghermez Anbori, Champ...
